This annual survey facilitated by Project Tomorrow gives
individuals the opportunity to share their viewpoints about
key educational issues — and to influence local, state and
federal policies and programs.
Since the inaugural survey in 2004, when it went by the name
NetDay, millions of students, educators, and parents have
shared their views through this national online research
project. This year, the survey asks students about their use of
mobile tools, social networks and gaming as part of their
learning in and out of the classroom.
Participants may request survey data from previous years here:

Download sample survey questions, flyers, and other
promotional materials — now available in Spanish — to help
spread the word:

PoW taking place: math problemsolving moment of the week

"Finding the answer was a long task that required a lot of
thinking. I first began brainstorming on how I could make this
problem simpler. There were four main reasons that make this
problem hard to figure out. First of all, ...."

 Justin, highlighted in the Geometry PoW's latest solution

The nonprofit, nonpartisan CEOled initiative Change the
Equation (CTEq) has begun assembling a database of "programs
that deepen young people's learning in science, technology,
engineering and mathematics (STEM)."
Search for math among STEMworks' program content areas, and
further refine by grade level, geography, target discipline,
target audience, design principles, and types of program
such as

teacher professional development

handson/projectbased

college readiness

informal/out of school
To recommend a successful exemplar for inclusion — subject to
independent review by WestEd — visit

Now taking place: math education conversation of the day

"WolframAlpha can handle Diophantine equations pretty easily
and can find integer solutions. But when the coefficients have
more digits, it cannot find integer solutions. Is there another
way to find integer solutions for equations like the above?"

Symbolab
http://symbolab.com/
A math search engine that considers the contextual meaning of
equations and expressions launched Monday.
Rather than return literally or visually similar matches,
Symbolab seeks out semantically similar results.
For example, Symbolab's proprietary machine learning
algorithms recognize that m refers to something different in
each of

E = mc² (here, m acts as an independent variable)

y = mx + b (a constant)

$\sum _{m=1}^{\infty }\left(\frac{1}{m^2}\right)$
(an integer variable)
Similary, the semantic search interprets the query (x + y)^2 as
equivalent to (a + b)(a + b) and to p^2 + 2pq + q^2 ; but
distinguishes x2 as different from x^2 or from x_2 .
In addition to an autocompleting text box, Symbolab invites
queries that mix text and symbols, such as
proof a^{n} + b^{n} = c^{n} , thanks to its pad, which toggles among

Greek letters

operators

differentials

"accents" (vectors, hats, degrees, notation for set
theory and logic)
Results pages include computation and graphs, where applicable;
the left margin lets you refine results into categories such as
"encyclopedia," "lecture and practice," and "online books."
Symbolab also offers users of the Chrome and Firefox browsers a
Quick Search extension:
